This study was conducted to determine the effect of various flooding du- rations on the growth, water relations, and photosynthesis of the snap bean (Phaseolus vulgaris L.). Greenhouse-grown plants of CV. Blue Lake 274 were flooded for 0 (con- trol), 1, 3, 5, or 7 days. Leaf water potential (ψ), stomatal conductance (gs), transpir- ation (E), and net photosynthesis (Pn) were measured at the completion of the flooding period and after recovery for 7 days. Root, stem, and leaf dry weights were… 
Flooding Affects Snap Bean Yield and Genotypic Variation in Leaf Gas Exchange and Root Growth Response
Greenhouse experiments were conducted in 1987 and 1988 to evaluate the effect of timing of a 4-day flooding stress on growth and yield of snap bean, finding that leaf conductance of BBL and another bean cultivar, Luna, declined within the first day of flooding.
Flooding Influences on Growth and Development of Bush Bean Under Greenhouse Conditions
Greenhouse data indicate that yield reduction can be estimated from changes in plant characteristics resulting from flooding, and linear relationships between yield components (pod number and weight) and flood duration, flood timing and leaf area are found.

The most ubiquitous plant abiotic stress in the global environment is generally thought to be water deficit. The opposite of water-deficit stress. flooding, initially involves relief of the abiotic
Influence of oxygen conditions on the yield and mineral composition of triticale cv. Jago
Plants in the farmland ecosystem are subject to impeded aeration at some stages in their development. The achievement of long term tolerance to prolonged periods of poor aeration by some plants holds
Effects of kinetin on growth, grain yield and some mineral elements in wheat plants growing under excess salinity and oxygen deficiency
It can be concluded that kinetin application helped wheat plants to grow successfully in the areas subjected to combined effects of salinity and oxygen deficiency, such as in salt marshes.
Effects of Waterlogging at Vegetative and Reproductive Growth Stages on Photosynthesis, Leaf Water Potential and Yield in Mungbean
Although even short-term waterlogging markedly affected P, Tr and rs of mungbean, the damage particularly in P and leaf growth was quickly recovered after the end of waterlogting and the reduction of seed yield was less than that expected from the damage in the physiological characteristics.
Growth and physiological responses of six barley genotypes to waterlogging and subsequent recovery
It is suggested that screening a small number of lines for waterlogging tolerance could be facilitated by selecting genotypes with least pronounced reduction of photosynthetic rate or total chlorophyll content, and for a larger number of Lines, chlorophyLL fluorescence is the most appropriate tool.
Root oxygen deprivation and the reduction of leaf stomatal aperture and gas exchange
The most ubiquitous plant abiotic stress in the global environment is generally thought to be water deficit. The opposite of water-deficit stress. flooding, initially involves relief of the
Effects of waterlogging on chickpeas II. Possible causes of decreased tolerance of waterlogging at flowering
There was no evidence that inadequate supply of carbohydrates or nitrogen in the stem, or increased sensitivity to ethylene, contributed to waterlogging intolerance in flowering chickpea plants.


Stomatal behavior and water relations of waterlogged tomato plants.
Experiments with varied time of flooding, root excision, and stem girdling provide indirect evidence for an influence of roots in maintaining stomatal opening potential, and ethylene-induced petiole epinasty develops coincident with partialStomatal closure in waterlogged plants.
We reviewed and compared several greenhouse studies on the effects of low soil oxygen (O2) levels upon plant response. The studies are discussed with particular reference to stomatal closure. Both
